ROOFNG SHINGLE.

Application illed July 26, 1926. Serial No. 124,882.

My invention -relates to roofing shingles and has particular reference to shingles of The principal object of this invention is to provide a flexible shingleI of asphalt slate type which may be apphed to a roof in such a manner as to entirely obviate the possibility of curling or other displacement.

A further object of the invent-ion is to provide a shingle of the character mentioned, in which .the so-called shadow. lines are of substantial thickness to give the appearance .of massiveness to the roof construction and in which such shadow lines bear the same appearance as the surface of the shingle proper. In asphalt slate shingles as heretofore made and used in the construction of roofs, the end ed s of such shingles which constitute the sha ow lines, constitute a sectional thickness of the shingle itself and therefore such edges expose the raw asphaltum of which `the shingle is basically constructed, said exposed edges thus contrasting with the surfaces of the shingles which are provided with sand or small particles of rock of ornamental color and appearance.

Another object of the above invention, as above stated, is to overcome this faulty appearance of the roof and to produce shadow lines of increased thickness and mass.

Further objects will appear from the following detailed description thereof:

In the drawings: A

Figure 1 is a perspective of a shingle constructed in accordance with this invention.

Figure 2 is a perspective of said shingle illustrating the method of its application to a roof.

Figure 8 is a perspective of a series of shingles as applied to a roof.

A shingle constructed in accordance with this invention consists of a strip of material 1 comprising a base 'of paper or felt impregnated with asphalt mastic upon which there are imbedded small particles of stone or sand 2, said features being of the usual construction known as asphalt slate shingles.

The novel features of construction comprise the elongation of the strip so as to provide anl underbent flange '3 of approximately onehalf the length ofthe strip and a narrow upnails 5 applied through the flange near the fold. The body of the shingle is then turned downwardly so as to rest upon the roof in the usual manner, and the next shingle is placed with the free edge of the flange 3 inserted below the upper flange 4 of the first shingle,

as shown in Figure 3. The body of the second shingle is lifted in the same manner as was done in the first shingle and nailed at the same point, said nails passing through the first shingle, as shown in Figure 3 of the drawings. Subsequent shingles are applied in the same manner, each series of subsequent nails passing through the three lshin-` gles so that when the roof is constructed of shingles of the above described design each shingle is secured to "the roof by means of three rows 'of nails, staples or other securing devices, one of which rows is near the bottom or exposed portion of the shingle, the other near the middle part thereof, and the third row at the upper end thereof. It'will thus be seen that allv shingles are rigidly secured and absolutely prevented from curling or warping.

By reason of the under-turned flange 3 construction, the shadow line edges 6 of the shingle are of turned construction andV of double or slightly more than double thickness of material of which the shingles are made. As theventire surface of the shingle furthermore, may be covered with the ornamental sand or'rock particles, the shadow line edges present the same ornamental appearance and thus add greatly to the beauty of a'roof constructed of such shingles, both by reason of the comparative massiveness or thickness of the shadow line edges as well as their presenting a uniform appearance` with the'surface of the shingles themselves.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent-is:

A roofing shingle of flexible type, comprising a body portion, an underturned flange at the lower end of said'bod portion, said flange being of substantially alf the length of said body portion, and a short upturned flange along the upper end of said body por- 5 tion, said lower flange being adapted to receive aline of nails adjoining the body portion, and said upper and lower flanges being arranged to interlock and being arranged to be so positioned with respect o the next higher shingle when laid, that the line of nails through the lower flange of said higher shingle,l will engage through the interlocking portions of the lower shingles.
